Answer to Question 1

(a) Carbon
With a ground-state electron configuration of 1s2 2s2 2p2 , there are four electrons in the valence shell of carbon.
(b) Nitrogen
With a ground-state electron configuration of 1s2 2s2 2p3 , there are five electrons in the valence shell of nitrogen.
(c) Chlorine
With a ground-state electron configuration of 1s2 2s2 2p6 3s2 3p5 , there are seven electrons in the valence shell of chlorine.

(d) Aluminum
With a ground-state electron configuration of 1s2 2s2 2p6 3s2 3p1 , there are three electrons in the valence shell of aluminum.
